Abstract

La presente divulgación generalmente se refiere a la identificación de superficies conducibles en conexión con la ejecución autónoma de varias tareas en sitios de trabajo industriales y, de manera más particular, a técnicas para distinguir superficies conducibles de superficies no conducibles con base en datos del sensor. Se proporciona un marco para la identificación de superficies conducibles para una máquina autónoma con la finalidad de facilitarle la detección autónoma de la presencia de una superficie conducible y estimar, con base en datos del sensor, atributos de la superficie conducible tal como la condición del camino, la curvatura del camino, el grado de inclinación o declinación, y similar. En algunas modalidades, al menos una imagen de cámara es procesada para extraer un conjunto de características a partir de las cuales se identifican superficies y objetos en un ambiente físico, y generar imágenes adicionales para procesamiento adicional. Las imágenes adicionales son combinadas con una representación 3D, derivadas de datos de LIDAR o radar, para generar una representación de salida indicando una superficie conducible.The present disclosure generally relates to the identification of driveable surfaces in connection with the autonomous performance of various tasks at industrial work sites and, more particularly, to techniques for distinguishing driveable surfaces from non-driveable surfaces based on sensor data. A framework for drivable surface identification is provided for an autonomous machine to enable it to autonomously detect the presence of a drivable surface and estimate, based on sensor data, drivable surface attributes such as road condition. , the curvature of the road, the degree of incline or decline, and the like. In some embodiments, at least one camera image is processed to extract a set of features from which to identify surfaces and objects in a physical environment, and generate additional images for further processing. The additional images are combined with a 3D representation, derived from lidar or radar data, to generate an output representation indicating a drivable surface.
